Select dropdownlist item after button click - vb.net

I have an asp drowndownlist and I'd like to change its selection after a button click. I can't seem to find a way to do this, is there a way? (Its a reset button of sorts, and I would like the dropdownlist to return to the "default" value.)


DropDownList.SelectedIndex = -1


In the click event can you do:
DropDownList.SelectedItem = "whatever";
DropDownList.DataBind()
?


Use
dropdownlist.ClearSelection()

Add domain in your many2one dropdown field.

Unable to Click on Edit Button , in WebTable

I am using xpath to click on edit button , but i dont know where the webtable starts so i can click on the webelement.
Below is the link for WebTable.
http://demo.automationtesting.in/WebTable.html
Thanks in Advance.

Try this:
// gets the first edit button
WebElement Edit_btn= driver.findElements(By.xpath("//div[#class = 'avddbl']/button")).get(0);
Actions action = new Actions(driver).doubleClick(Edit_btn);
action.build().perform();

If you want some specific selection e.g. want to edit info of particular user
Then you can use below xpath where you have to changes email address only it will click on the edit icon of that particular record .
//div[text()='steven#hotm.com']/../following-sibling::div//div[#class='avddbl']/button[contains(#class,'btn')]

MS Visual Studio - How do I use a button to Sort my combobox variables?

I searched and only found how to sort combobox variables through the Properties sidebar. This will not work for what I'm trying to do.
I have a textbox where the user will type in a name. They click the Add button, and the name is added to the combobox options. Let's say I add "Bob" then "Andy" then "Carl". In the combobox it would list them in that order.
I need to use a button that will sort these names alphabetically. How would I do that?

Instead of changing the "Sorted" in properties to true, I set it so that when you click the button, it would do this. So the "Sort" button code would look like this:
ComboBox1.Sorted = True

Put them in an array and use Array.Sort then back into the combobox

Selecting button in Winform ToolStrip

Reference Image
I want to select a button("Exit") on the ToolStrip after pressing a button ("ButtonFocus To Exit") outside the toolstrip.
I used ExitToolStripButton.Select() on ButtonFocusToExit.Click but which seems like its selecting the button ("Exit") but when i pressed enter it never execute the code in "ExitToolStripButton_Click" .
So the button is still not active. Can anyone have fix to it?

Got the solution ...
First focus on the ToolStrip and then Select the Control on the Toolstrip
ToolStrip1.Focus()
ExitToolStripButton.Select()

Check if event is missing the event handler
Select the ExitToolStripButton > go to
properties > events tab> Click Event >
select the ExitToolStripButton_Click

You want to execute the ExitToolStripButton codebehind? You can call ExitToolStripButton.PerformClick();

Make sure it has focus. Are you sure the function you are using actually give the object focus? It could just give it the appearance of selection.
According to MSDN:
Select | Selects the item. (inherited from ToolStripItem)
It doesn't say anything about focusing it.

Determine if an item is selected in a listview box

Using VB.net 2010 i am trying to figure out if an item was selected or not. Reason being is that if the user clicks on an item and pushes a button then everything works just fine. However, if the user selects an item and then clicks on a blank spot on the bottom of the listview and then clicks the button then it crashes.
My code is this:
If (lstMaster.SelectedItems(0).SubItems(1).Text) Is Nothing Then
MsgBox("test")
End If
Any help would be great! :o)

Ensure that something is selected first by checking that SelectedItems is not empty.
lstMaster.SelectedItems.Count > 0

check lstMaster.SelectedItems(0).Selected

Not sure if I've understood you correctly - Try using the ListView MouseMove event and check that lstMaster.SelectedItems.Count > 0 if you want to change the Enable property of a Button based on whether a row has been selected or not within your ListView control.

Use this checking with "If/EndIf" construction:
ListView1.Items(0).Selected = True
